Helen is standing in the hallway with her friend Janet, next to Helen's locker. Each girl has a body mass of 48 kilograms (kg),
and thus each exerts a force of 470.4 Newtons (N) on the hall floor. What is the total force, in Newtons (N), that the hall floor exerts on the pair of girls? A. 940.8 N
B. 96 N
C. 960.4 N
D. 48 N
The right answer for the question that is being asked and shown above is that: "A. 940.8 N." Helen is standing in the hallway with her friend Janet, next to Helen's locker. Each girl has a body mass of 48 kilograms (kg), and thus each exerts a <span>force of 470.4 Newtons (N) on the hall floor.</span>
The ans is c. This is theoretically speaking. Experimental wise would be slightly different. That is because not all the reactants may have fully reacted. Hence, if you are speaking about theory-wise then the ans would be c. But in actual, it would be D.
